| 摘要 |
A medical device with a self-sustaining power source is disclosed herein. The medical device includes e.g. a medical skin-patch type infusion pump having at least one mechanical and manual activation mechanism, e.g. comprising buttons (16, 18), for engaging the pump to cause a dose event. An energy generator, e.g. energy harvesting system based on a piezo crystal (402) mechanically coupled to a fixed portion (24) of the medical pump, coupled to the activation mechanism generates energy each time the activation mechanism is actuated. The generated energy is supplied to a dose counter of the infusion device. |
